The third generation of inverter arc power supplies means a high power factor, efficiency and compliance with EN61000-3-12 standard for harmonic currents produced by equipment connected to public low-voltage systems as well as compatibility with EMC and PFC power systems. Innovative and lightweight  yet highly durable devices are intended for MIG/MAG, Puls, MMA and TIG welding. The devices are equipped with intelligent and intuitive functions to control voltage and current parameters using the QSet process and True Arc Voltage welding voltage stabilization. All functions are available in the control panel U6 and U8. QSet – a function that automatically optimizes voltage and current parameters in the short arc area regardless of the type of welded material, wire diameter and shielding gas.
